[Desire HD Q&A, Help & Troubleshooting] superstick1:
Hi there, the current CPU max for Desire HD on stock is 1GHz.

If we change to other custom ROMs and it allows us increase the normal 1GHz to say, 1.5GHz.. (overclocking?) will it damage our hardware?

Cause as far as I know the software should be supported with a powerful hardware as well.
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
Overclocking always has the possibility to damage the cpu. And as not all cpu's are the same, if you want to overclock, the best way is to start of slowly say 1.1ghz. And keep stepping it up slowly. If your device begins to get unstable, go back a step, and you will pretty much know the level of your cpu :) fyi ive had mine overclocked to 2ghz and it seemed to run fine, although i didnt keep it at that level for long. lol
[Desire HD Q&A, Help & Troubleshooting] KAsp3rd:
I've been using minne over clocked at 1.5ghz since the day I bought it and I've not noticed anything as far as hardware failure. Being a computer technician I'm constantly trying to run what I have at the fastest rate without fail. I've not felt any overheating and per temps I've only seen about a 5-8°c increase over another user at work on the same ROM.
[Desire HD Q&A, Help & Troubleshooting] wismerhull:
I have been running mine DHD at 1,2 for some time and ofc there is a chance that the CPU fries, because of the OC, but I don't think the chance is very big.

But please remember that the warranty of the phone dosn't cover overclocking ;)
[Desire HD Q&A, Help & Troubleshooting] superstick1:
Hmm.. ok. Thanks for the advice.

I shall consider carefully before doing anything. Currently I am at only 1190MHz. Lol.

Anyway thanks again. :D
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Well,I am running a really nice 1.8GHz,stable and fast as hell.Never noticed any overheating.

What most people should bear in mind is that the physical limits of our cpus aren't the ones that the manufacturers tell us they are with their spec sheets.Almost always,cpus are tested in higher clock speeds than what they are sold with,just to be stable and safe. :)

And one more thing.Correct me if I'm wrong,but doesn't the Flyer share the same cpu as the DHD?Cause it runs @1.5GHz stock.If they have the same cpu,guess what this means for us! ;)
[Desire HD Q&A, Help & Troubleshooting] alpine17:
In my, I can use up to 1190, higher - websites in flash crash :(

ROM: Android Revolution HD 2.0.16

Kernel: Buzz OC/UV 1.61Ghz

What is a good program to test CPU stability ?
[Desire HD Q&A, Help & Troubleshooting] tolis626:
In setcpu,go to the info tab and do a stress test for some minutes.If it doesn't crash or anything you're good to go! ;)
[Desire HD Q&A, Help & Troubleshooting] alpine17:
Thanks.

I did two ten-minute tests in SetCPU, the first 1,53Ghz and second 1.61Ghz, both without errors.

Anyone have any idea ?
[Desire HD Q&A, Help & Troubleshooting] superstick1:
Lol. Guess I will just try increasing the GHz slowly. Trying 1.3 now :D
[Desire HD Q&A, Help & Troubleshooting] Tones1971:
I dived straight in, and set it to 1.5. No problems so far. Done a stress test successfully. But is there any need to increase the minimum level?
[Desire HD Q&A, Help & Troubleshooting] Flussen:
If you clocked your cpu too high, your complete phone will freeze. That means the only possibility to restart it is by pulling the battery.

If your browser closes suddenly without any notification, it's app related and not due to an overclocked cpu.
[Desire HD Q&A, Help & Troubleshooting] benno4403:
Can i overclock my HTC Desire HD when I still have the standard vodafone rom on it?

Can someone tell me how to do this pls?

Thnx
[Desire HD Q&A, Help & Troubleshooting] tolis626:
You're right pal.I don't remember who asked,and am too bored to look for it right now,but it also happened to me with stock unrooted rom. :)

Well,to overclock you'll need a custom kernel,which means you'll have to be rooted and have at least clockworkmod recovery installed.ENG and Radio S-OFF are recommended. :)
[Desire HD Q&A, Help & Troubleshooting] alpine17:
ok I know, but I do not understand why when I enter the page, for example: speedtest, after a few seconds the phone is completely frozen (o / c) 1.22Ghz

I watch movies, play games, do tests, benchmark, etc. (o / c) 1.22 Ghz - 1.53Ghz. Everything is ok.

just a few seconds in the flash player and death: :(
[Desire HD Q&A, Help & Troubleshooting] catevs:
Did someone try do downclock CPU to say 800MHz. Will it improve battery life?
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
Yes you can, you need to root, s-off and install a custom kernel first though.
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
Yes underclocking will improve battery like, at the cost of performance :)
[Desire HD Q&A, Help & Troubleshooting] AndroHero:
Flash it quite a cpu intensive task, thats why :)
[Desire HD Q&A, Help & Troubleshooting] tolis626:
Well,as AndroHero said,Flash is quite CPU intensive.However,your problem could be caused by the fact that your CPU isn't as "good" as others.By "not good" I don't mean that your CPU's quality is bad,it's just that it is unique like every CPU(nanometer scale devices like transistors are hard to be produced and be exactly the same one with another) and it might need you to up the voltages for higher frequencies.That by itself is no problem.

If the problem is indeed your CPU's limits,as it could be app related as Flussen said,and if you are running LeeDroid's rom or at least have his kernel installed,I could provide you with the OC script I am using myself.You see,I too am "suffering" from problems with the CPU not being able to handle too high overclocks,so I had to up voltages.Fortunately not much! :D

Well,in theory it should improve battery life.But calculating battery performance is a hard and tricky process.Just think about it this way;The CPU will run at lower voltages while at its reduced max frequency,thus needing a smaller electric current.However,it will need to run at the max speed for a larger amount of time.So,what you finally get is reduced drain,but for longer periods,meaning the gains in battery life could be minimum to non-existent.I for one am running 1.8GHz and battery life is just as good as @1GHz. ;)
[Desire HD Q&A, Help & Troubleshooting] dlads:
It's dependant on you and what you want to do with your phone, if you just want day to day usage then the undervolted 1.2ghz kernels are great for that and it improves speed with minimal (if anything) impact on your power consumption, you can overclock like someone has replied up to a max of 2ghz i think, might be more but why would you want to besides bragging rights.

There is always the possibility of something going wrong when overclocking any cpu /gpu. You will be making a piece of hardware work harder than it should and like it's been said before all cpu's are different and some may yield better overclocks than others.

Try to see whats safe and then find a practical OC', like i said before a 1.2ghz oc /uv works for me.
[Desire HD Android Development] DOAlaboratories:
I've compiled a kernel for Cyanogenmod 7 from Kali's sources that OC's up to 1.8ghz and has a minimum of 122mhz (along with a few other tweaks I forgot about). Just use setCPU. It's pretty much Kali-'s kernel, but with a few minor config changes that I just had to enable. If you feel the need to donate, please donate to Kali- as I just changed around a few files. A few more tweaks will come around as soon as I have spare time (school's a b*tch sometimes and I have a tattooing apprenticeship to juggle). Just request what you guys want for the next version and I'll do my best to add it.

Thanks to Kali- and the rest of the cyanogenmod team for creating our port, and to everyone who helped them out. Hope I'm not violating anything by posting this.

maybe some benchmarking results?? XD How's the battery like??
[Desire HD Android Development] DOAlaboratories:
2700 on benchmark full OC'd. Screens coming soon. battery seems to be good so far, not too much extra drain.
[Desire HD Android Development] Rey-619:
Plz add 122 Mhz on 850 mv and make it suitable to MIUI... i will love you ^^
[Desire HD Android Development] DOAlaboratories:
was 122 proven stable yet? let me recompile, test, and if it comes out good I'll add.
[Desire HD Android Development] Rey-619:
i had no problems ore crashs.

used min/max 122Mhz
[Desire HD Android Development] DOAlaboratories:
Thanks for the request, I'm about to test it as soon as it finishes compiling. :)
[Desire HD Android Development] DOAlaboratories:
122mhz seems stable, I'll upload after I sleep, and a little testing.
[Desire HD Android Development] starbase64:
Hi,

wifi wont work on cm nightly 8 :(

with friendly greet

starbase64
[Desire HD Android Development] DOAlaboratories:
whoops. I know where the problem is. I need to recompile the module from nightly 8 and I'll have her up and running as soon as the source downloads
[Desire HD Android Development] Rey-619:
i changed the name for the wifi modul and reuploaded.

Hope it is working now

http://www.4shared.com/file/ldGnevEj/CM7OC_10.html
[Desire HD Android Development] DOAlaboratories:
Thanks :) let me add that module to 1.1 and test real quick
[Desire HD Android Development] starbase64:
Hi,

i've already tried, but nothing.

with friendly greet

starbase64
[Desire HD Android Development] htctouchelfin:
So is working or not on nightly 8?
[Desire HD Android Development] DOAlaboratories:
The wifi's broken until I can find the nightly device source... :( can any o you guys point me in the right direction?
[Desire HD Android Development] htctouchelfin:
I'am sorry but i don't know what is it...
[Desire HD Android Development] Rey-619:
so far so good actually wifi is still broken

Adb does work on MIUI builds but showing nothing in the notification bar.

USB does not work!

But performance is very nce ^^

first run with I/O patch muhaha
[Desire HD Android Development] DOAlaboratories:
I just need the source for the nightly. Sorry for borking the wifi guys, I've only been compiling kernels for about three days and this was the first one that actually compiled. I'm new, so bear with me here :(
[Desire HD Android Development] Rey-619:
give it time ^^ we are testing for you :D

i just hope somen bare himself to make an fully working miui kernel -_-
[Desire HD Android Development] xd4d3v:
sorry if my questions are a little bit dumb, since i've never replaced a kernel.

1) how to install this kernel? I'm running CM7 RC1

2) any way to check the cpu temps while OCcing (just so we dont fry the CPU)

3) what's MIUI i read before?

thanks in advance.
[Desire HD Android Development] DOAlaboratories:
No problem.

1) just download the file, move it to your sdcard, and install with ROM Manager (although wifi is broken right now with it)

2)I believe SetCPU has an option for that

3)I belive it's an AOSP 2.2.1 froyo build, someone correct me if I'm wrong
[Desire HD Android Development] Rey-619:
3. its an chinese ROM you also can take a look into my signature for more informations
[Desire HD Android Development] xd4d3v:
wow, this kernel is fast.

I installed first over my CM7 (which was not going so smoothly) and did a Quadrant, and got less than 2000.

I reflashed the CM7 RC1 and cleaned the cache and data, and reflashed the kernel.

now it's up to around 2600.

wow.

PS: setcpu seems to do the same as the performace menues on cm7?
[Desire HD Android Development] DOAlaboratories:
IT'S FIXED!! 1.1 uploading.
[Desire HD Android Development] kendong2:
could you please add a link to the sources you used?
[Desire HD Android Development] Rey-619:
wow fast :) ok

so:

122Mhz does work well

Wifi is working on MIUI

BT is working on MIUI

ADB does not show but is fully working

USB dos NOT work :(

i hope you can fix this for me!!!

Seems like no kernel dev likie MIUI... nobody does fix that issue for me :(((

BTW: For MIUI users:

Network does dissaper when locking phone:

just push this file to /sytem/lib/

http://postkreative.eu/libhtc_ril.so
[Desire HD Android Development] DOAlaboratories:
I'm sending them to my github right now
[Desire HD Android Development] DOAlaboratories:
I would help if I knew where to start on MIUI... I've never worked with it before. so far i've only compiled from htc sources and CM sources.
[Desire HD Android Development] Rey-619:
mhm.. im not realy an dev, so i only can say what problems i have.. sry

MIUI is nearly complete close sourced :(

I just can say that the sense kernels from buzz and leedroid are nearly working except BT -> thats all what i know

i think we need an "mixed" kernel out of cm and sense o_0
[Desire HD Android Development] DOAlaboratories:
it may be the bluetooth drivers then. I'll examine it when I get a chance, I'm doing 6 hours of school and 4 at a tattoo shop so I'm pretty busy.
[Desire HD Android Development] Rey-619:
thats no problem, i can wait! i realy hope you can get this!!
[Desire HD Android Development] MrGarak:
The latest stock MIUI kernel at 1.51Ghz is actually working very well, will be interesting to see if this becomes compatible though, those benchmarks were nice :)

Would be really nice to get a good solid custom kernel for MIUI.
[Desire HD Android Development] ArtaxXP:
Thanks for your work m8!

Works like a charm =)

edit: sorry...wlan still does not work for me... :(
[Desire HD Android Development] hammer31:
anyone crash phone at 1800ghz??
[Desire HD Android Development] ArtaxXP:
no crashes at all but...hmm...wlan still does not work.... :(

edit: after flashing the kernel a second time, wlan now works =D
[Desire HD Android Development] curtis2k10:
Crash Report

Kernel: 1.1

ROM: CM7 #8

Details

Installed kernel via cwr, rebooted device and changed setcpu values to min 122mhz and max 1.8ghz. Enabled wifi, ran quadrant twice and on the second result screen I pulled down the notification bar a few times and the device froze, rebooting itself 5mins later.

Update

The device also crashed when running linpack multiple times. Got it up to 60+ but it states Inaccurate result under precision.
[Desire HD Android Development] kendong2:
it is physically not possible to run a processor at this speed, not today and probably not ever.
[Desire HD Android Development] htctouchelfin:
cm7 nightly 8 + 1.1 kernel

wi fi ok

somethimes crashes at 1.8 but i think is normal.
[Desire HD Android Development] ArtaxXP:
3000 points with antutu system benchmark...4 benchmarks done, works extremely stable for 2 hours now...

but still no wlan...
[Desire HD Android Development] chchang1:
there are processors running at like.....8 GHZ.....
[Desire HD Android Development] kendong2:
which is far from the aforementioned 1800 GHz, and well within the physical limits.
[Desire HD Android Development] Jordan5222:
how many mV at 1.8 ghz? i wanna try this :D
[Desire HD Android Development] ArtaxXP:
i think he wanted to write MHz not GHz ;)
[Desire HD Android Development] kuceens007:
there`s no need to use your cpu at so high level.. it only damages it!! we have no apps at moment which need so high cpu :cool:
[Desire HD Android Development] kendong2:
yeah right, as if that ever was an argument ;)
[Desire HD Android Development] buzzboy:
My Desire is flying I can tell you, running Cm7 "Extra fluffy" which was fast already. Holding back the temptation to use the nitros too much though.

Thanks
[Desire HD Android Development] K Dotty:
Using this kernel and it is fast crashed a couple times on 1800ghz after flash but it seems to of settled in nicely. got a bench of 2680 but it usually takes a couple days to run properly.

Thanks XD
[Desire HD Android Development] DOAlaboratories:
Who's still having problems with Wifi?

And what features would you guys like to have in 1.2?
[Desire HD Android Development] sipdawg:
Is this kernel for daily use?

It runs ok. But i wonder if it wil screw up my cpu when i use this for a long time.

I have >temp enabled in setCPU at 50 degrees. So guess thats safe then?
[Desire HD Android Development] xd4d3v:
how did you enable setcpu temp thing? can't find it anywhere! thanks

-------------------------------------------------------------------

Nevermind, I found you need to create a profile for this.

I created one with temp >50C to go to 122Mhz-1Ghz

Anyone has any profiles to share?
[Desire HD Android Development] kshting:
:D Gonna flash this tonight...goodie goodie!:cool:
[Desire HD Android Development] kshting:
Erm........2GHz in 1.2:D
[Desire HD Android Development] xd4d3v:
yes, you can fry eggs on the back of the phone :-p
[Desire HD Android Development] kshting:
:confused::D:p

Great as a camping tool or survivor kit.

Hi! Thx for this great kernel first of all.

Also could you add the VDD LEVELS patch so then we can adjust the voltages on the fly??

Thanks!

wouldnt it be better to use avs instead of vdd levels?
[Desire HD Android Development] kshting:
I really feel that it is not necessary, since its not going to make a significant overall improvement to the battery life. This kernel as it is, is already great.

Anyway, I guess with this patch, user(s) would now have the option to set their own vdd levels, provided most would know how to use it appropriately.

Just my opinion, no offence to anyone here. Cheers!
[Desire HD Android Development] funkatiko:
No offence at all. I just disagree with u. We all know that CM has a drain battery issues, much more than sense. I just think any help to save mA is needed. Also u always have the choice for doing it or keep using the stock voltage from the kernel. I tested a lot with this and my device can handle really nice and low voltages, and very stable, personally i'd love to do the dame with CM7. It's up, of course, to the developer. I hope he does it :) thaaaanks!
[Desire HD Android Development] kshting:
Yes, battery issue on cm7, I agree with you. And yes, as I mentioned before, it now has become an option for user(s).

Anyway, all the best to you in saving as much mA with this patch.

Cheers!!

v1.2 results:

1.8ghz, interactive governor

Quadrant: 2547, 2831, 2900

Linpack: 60.97, 61.506 (inaccurate result), 58.218, 61.237

SetCPU stress test: 5 minutes no reboot (haven't tested for longer than 5 minutes)
[Desire HD Android Development] -Android Freak-:
Its working great. Running @ 1.8GHz performance and have been running stress test for 6.5 minutes @ 100% CPU load, no problems at all. 33.3 degrees Celsius on the battery while charging. Can't see CPU temp but probably not even 50 degrees. This new 45nm CPU seems to be incredibly effective. And all you guys saying there's no need for this speed can just zip it, and those claiming the CPU will burn or get destroyed... get a clue. You don't know what you're talking about. Frying eggs on the phone? Really? *facepalm*

Request: enable 2 GHz. Let's see how far we can push this.

I'm volontueering for beta testing.
[Desire HD Android Development] funkatiko:
Thanks i guess although it seems sort of ironic?

It's not only about the mA...anyway...hope to see this made.

[Desire HD Android Development] -Android Freak-:
Please read about overclocking in general before asking very very basic questions.

http://en.wikipedia.org/wiki/Overclocking

Your CPU is not "broken" it's just not a "good" overclocking CPU you got. That is actually insane to say becuase if it works at 1.6 GHz, that is 60% increase in speed. That is ridiculously good and not something you see very often. But the new 45nm architecture of the Snapdragon II is absolutely stellar.

I have a Operton 175 CPU at home that I cool with liquid Isobutan (phase change cooling) to below 30 degrees celsius (-22 farenheit) and it still wont overclock more than 25%. Take that in comparison to your 60% increase... And that is with no additional cooling.

PLEASE learn a bit about overclocking... at the very very LEAST read the wiki on overclocking before asking stupid and off topic questions. Otherwise you really shouldn't be doing this kind of stuff.
[Desire HD Android Development] lodger:
At last someone with a bit of sence, why do people moan because there phone will not overclock as high as someone elses, I would be over the moon if i could overclock my i7 to 60 present.
[Desire HD Android Development] Rey-619:
definitly not! ;) normal value is 1Ghz.. and this works fine, does it?

All over this value, you must see as an extra candy.
[Desire HD Android Development] htctouchelfin:
trying last kernel, for me is impossible to reach 1,8 because everytime it crash at this voltage
[Desire HD Android Development] ArtaxXP:
works perfect for me...ondemand 122mhz - 1804mhz...no crashes since first release v1.0.

antutu system benchmark with 3032 points :D
[Desire HD Android Development] ArtaxXP:
would you give it a try to go to 2,0 GHz ?
[Desire HD Android Development] -Android Freak-:
I have already requested the 2.0 GHz stepping to be enabled.

I'd try higher still, all the way until it freezes. I want to go to the absolute limit of what this little guy can handle. I've been overclocking stuff since years and the worst I have ever gotten from OVER-overclocking is a frozen system.

I've been running most of my CPU:s and GPU:s overclocked for years on end and NO DAMAGE whatsoever has come to them. If this litle guy pops and melts then I'll laugh and buy a new one. (highly unlikely)
[Desire HD Android Development] DOAlaboratories:
The next release should make the OC quite a bit better and more stable ;) I'm ironing out the bugs atm
[Desire HD Android Development] franklin20uk:
yea, these phone cpu are probably built quite differently from desktop cpu anyway, so even if clocked at 1.8Ghz, you can't really compare a intel chip running at 1.8Ghz. Phone cpu are probably much smaller and and using much lower standard volt then desktop cpu, so the risk for frying it is low.
